I just had 4 wisdom teeth extracted last week. And I recommend soft foods like: noodles, soups, scrambled eggs, porridge, cottage cheese, etc. for the first 3-4 days after getting the extractions. After that it just depends on how fast you recover and how your mouth is feeling.
***DO NOT eat things like rice and potato chips as they can get stuck in the wound and cause an infection.***
After 48 hours you can start eating normally. If there is swelling, eating soft foods is a better idea.
Also, if food gets stuck in the holes, rince with water and salt, or use a plastic syringe to clean the holes.
